On obscure Commodore 64 game The Red Obelisk:

In 1987, programmers Robert Germino and David Todeshini wrote a weird and obscure Commodore 64 game called The Red Obelisk. It barely made a dent in the market, which is kind of a shame. It's nearly entirely unique, which is a difficult thing to say of any game 36 years after its publication.

Part of why it's not remembered much today might be how unique it is. It's mostly a game about alchemy, but not as much in an Opus Magnum kind of way. You're given an object, kind of like a gemstone, found in an asteroid belt. You shock it with electricity, zap it with lasers, and shoot sound waves at it. All of this is depicted in an illustrated laboratory, with surprisingly atmospheric graphics and sounds. Doing these things may increase its value. You can sell it at any point to earn energy proportionate to its value, which you need to run your ship and guard against hazards, and points. Your real goal though is to create a Red Obelisk.

On foundational CRPG Wizardry: Proving Grounds of the Mad Overlord:

All of these party-based CRPGs have a lineup, a list of characters that are generally considered to be in order. Dungeon Master arranges them in more of a 2×2 grid, but there's still a front line and a rear. Key in all of these games is that the front line is where you should put your melee fighters, who are in substantially more danger and need more HP and equipment protection (often directly using the D&D term Armor Class). The rear is where the characters who can't take a licking go: the thief and your mages. Clerics/Priests generally can go in either area. By tradition they they can still still use most armor, but the problem is they're usually the party healer, so being in the front line also means they're more likely to get taken out by Paralysis or Petrification, leaving the rest of the group in the lurch.

It's vitally important that the front line holds. Characters who get knocked out will get automatically shuffled to the back of the group, putting the squishies in range of the monsters' unkind claws and teeth. It might be possible to hurriedly cast some AC-increasing spells, but it's usually just as fast to cast strong attack magic and end the fight, then cure the downed fighters in camp. If you can't do that… well, then it's best to find your way back to town by the most expeditious route.

On Super Mario World's score display:

Awesome Mario trivia blog Supper Mario Broth noted on Mastodon that Super Mario World is extremely inefficient in displaying Mario's score.

There is more information on SWMspeedruns.com, but in brief, SMW stores the player's score as a 24-bit value as hexadecimal digits, and converts that value to decimal when it's time to display it. There is no good way to do that that doesn't involve figuring out the entire arithmetic, but Super Mario World does it particularly slowly: it starts with a copy of the score, then sees if it's over 1,000,000. If it is, it increases the millions digit of the displayed score by 1, subtracts a million from the work value, then repeats. When it runs out of millions it repeats with the hundred-thousands, and repeats until it finishes with the tens. At least it doesn't try it with the 1s, seeing as how nothing in the game awards single points!

In a worse-case scenario, with a score of 9,999,990, the code goes through this whole process every frame, consuming up to 8% of the time available for game logic.

On Rampart:

In the late 80s Atari Games was recovering from 1983's Great Game Crash, which decimated the US arcade industry and resulted in a great dying out of companies. Atari Games, newly split away from the consumer electronics company that would make the Atari ST, weathered it better than most, primarily through developing ingenious kinds of games the likes of which were seen nowhere else.

This period, 1984-1990, is the age that began with Marble Madness and the System 1 hardware, followed by hits like Paperboy, 720 Degrees, Gauntlet, Toobin', Cyberball and others. It lasted roughly to the release of Street Fighter II, which sparked the fighting game craze and made arcades inhospitable to most other genres for a while. At the tail end of this period came Rampart, designed by John Salwitz and Dave Ralston, who also created three of the games in the foregoing list.

It's a bit obscure now, but it was quite a hit for Atari at the time. For home systems Rampart received no less than thirteen distinct ports, plus a few notable emulations. It got very good reviews from Nintendo Power (SNES version) and Videogames & Computer Entertainment (arcade). More recently, it was released emulated with network play for free for the PlayStation 3. And yet, still, no one talks about Rampart anymore.
